Paypal verifies your account because they need to know their customers. Since they are involved in financial transactions, they need to comply with rules and regulations set up by the respective governments and financial institutions.
Please write to them to know the estimated time frame they need to activate your PayPal account after document submission.
You can visit the website paypal.com, and look for the email address or other contact details they must have. The support team there will also tell you what documents they require from you.
By the way, this is the link I found on their website: https://www.paypal.com/in/smarthelp/contact-us
Hope this helps!
